The embodiment of the application aims at solving the technical problem that the opening ratio of the liquid crystal display device is low due to the fact that the width of a black matrix is large in the conventional liquid crystal display device.
As shown in fig. 1, in the conventional liquid crystal display device, in order to avoid distortion of a display screen caused by stray light between adjacent pixels, a black matrix is disposed between the adjacent pixels, the color barrier layer includes a red color barrier 111, a blue color barrier 112 and a green color barrier 113, a lateral distance between the adjacent color barriers is a1, and a longitudinal distance between the adjacent color barriers is b1, but in order to avoid scattering of stray light, a via hole 121 formed by the black matrix layer 12 is smaller than the size of the color barrier, that is, a lateral distance a2 between the adjacent via holes 121 is greater than a1, and a longitudinal distance b2 between the adjacent via holes 121 is greater than a2, so that the black matrix can block the color barrier, and an actual light emitting area is smaller than a light emitting area of the color barrier, thereby reducing an aperture ratio of the display panel.
As shown in fig. 2 and 3, an embodiment of the present application provides a liquid crystal display panel, which includes:
a first substrate 23;
a second substrate 21 disposed opposite to the first substrate 23;

The embodiment of the application provides a liquid crystal display panel, wherein a shading layer is arranged in the direction of a first substrate away from a liquid crystal layer, shading patterns are formed on the shading layer in a patterning way, the shading patterns are arranged between adjacent pixels, the difference value between the width of the shading patterns and the interval between the adjacent pixels is smaller than or equal to a threshold value, and the material of the shading patterns comprises inorganic materials, so that the area between the adjacent pixels is shaded through the shading patterns, a black matrix is not required to be arranged, the control capability of liquid crystal is improved, and the shading patterns are arranged outside the substrate, so that the human eye side is shaded, the width of the shading patterns is not required to be larger than the interval between the adjacent pixels, and the aperture ratio of the liquid crystal display panel is improved.
It should be noted that in the design of the liquid crystal display panel, there may be a case where the pitch between adjacent pixels in the lateral direction is different from the pitch between adjacent pixels in the longitudinal direction, that is, in fig. 3, c1 and d1 are not equal, the comparison between the width of the light shielding pattern and the adjacent pixels is determined according to the direction of the adjacent pixels, for example, the adjacent pixels are two pixels in the longitudinal direction, the width of the light shielding pattern is d2, the adjacent pixels are two pixels in the lateral direction, the width of the light shielding pattern is c2, that is, the width of the light shielding pattern corresponds to the pitch between the adjacent pixels; meanwhile, the situation that the interval between the adjacent pixels is unequal is also caused, the corresponding design is carried out on the width of the corresponding shading pattern, so that the shading pattern shades the area between the pixels, and meanwhile, the shading pattern is prevented from shading the pixels by controlling the width of the shading pattern, so that the aperture ratio of the display panel is improved; whereas, in the case where the pitch between the adjacent pixels in the lateral direction and the pitch between the adjacent pixels in the longitudinal direction are the same, that is, c1 and d1 are equal in fig. 3, the width of the light shielding pattern is either one of c2 and d 2.

In the embodiment of the application, compared with the prior art that the black matrix is arranged in the substrate, because the black matrix is made of organic materials, the black matrix can be contracted in the forming process of the organic materials to form a state that the two sides of the middle recess are convex, so that the liquid crystal has a certain pretilt angle (the pretilt angle refers to the deflection angle of the liquid crystal caused by design defects outside the design), thereby influencing the display, such as light leakage, and the liquid crystal cannot be effectively controlled.
In one embodiment, a first alignment layer is disposed on the first substrate, and a second alignment layer is disposed on the second substrate, that is, when the liquid crystal is aligned with the cell, the alignment layers are formed on the first substrate and the second substrate, so that the liquid crystal is aligned by the alignment layers to form a certain pretilt angle, and light is controlled by the deflection of the liquid crystal.

In one embodiment, as shown in fig. 2, the first substrate includes a color film substrate 23, the color film substrate 23 includes a second substrate 234 and a color resist layer 232 disposed on the second substrate 234, and a common electrode layer 231, adjacent color resists are disposed at intervals, the light shielding pattern 241 is disposed on the second substrate 234 in a direction away from the color resist layer 232, when the light shielding layer is disposed, for a liquid crystal display panel with a light emitting direction being a color film substrate side, by disposing the light shielding pattern on the color film substrate side, the light shielding pattern shields an area between pixels from stray light, so as to avoid the influence of stray light on display, and since the light shielding pattern is disposed on a human eye side, light does not pass through other film layers to cause refraction or offset of light after being emitted from the color film substrate side, therefore, a black matrix is not required to be disposed, and only a difference between a width of the light shielding pattern and a color resist is smaller than a threshold value, so that the light shielding can be performed on stray light, thereby improving an aperture ratio of the liquid crystal display panel.
In one embodiment, the liquid crystal display panel includes a terminal area, and the light shielding pattern is disposed along a direction perpendicular to a region where the terminal area and the terminal area are opposite, that is, when the light shielding pattern is disposed, the light shielding pattern may be disposed laterally, so that between adjacent pixels in a longitudinal direction, by disposing the light shielding pattern, a black matrix is not required, thereby improving an aperture ratio of the display panel.
In one embodiment, the liquid crystal display panel includes a terminal area, and the light shielding pattern is disposed along a direction of an area where the terminal area and the terminal area are opposite, that is, when the light shielding pattern is disposed, the light shielding pattern may be disposed longitudinally, so that between adjacent pixels in a lateral direction, a black matrix is not required to be disposed by disposing the light shielding pattern, thereby improving an aperture ratio of the display panel.
In one embodiment, as shown in fig. 3, the light shielding pattern 241 includes a first pattern disposed transversely and a second pattern disposed longitudinally, where a width d2 of the first pattern is equal to a spacing d1 of adjacent color resistors disposed transversely, and a width c2 of the second pattern is equal to a spacing c1 of adjacent color resistors disposed longitudinally, that is, when the width of the light shielding pattern is set, the width of the light shielding pattern is equal to a spacing between adjacent pixels, so that when the display panel displays, a region corresponding to the color resistors can be completely displayed, and the light shielding pattern shields the region, so that the display panel is not affected by the emission of stray light, and the aperture ratio of the display panel is improved.
In one embodiment, when the light shielding pattern is made to shield the area between the adjacent color resistors, the width of the light shielding pattern may be made to be larger than the interval between the adjacent color resistors in consideration of better light shielding property, and since the light shielding pattern is made to shield the light on the human eye side, even if the width of the light shielding pattern is larger than the interval between the adjacent color resistors, the width of the light shielding pattern is smaller than the width of the black matrix compared with the light shielding of the black matrix on the light emitting side, so that the aperture ratio of the liquid crystal display panel is improved, when the width of the light shielding pattern is equal to the interval between the adjacent color resistors, the light shielding effect of the light shielding pattern is the same as or even better than the light shielding effect of the black matrix, and when the light shielding property is required, the width of the light shielding pattern is slightly increased, but the aperture ratio of the display panel can be still increased, and the display effect of the display panel is improved.
In one embodiment, when the shading pattern shades light between adjacent color resistors, in consideration that when the width of the shading pattern is smaller than the interval between the adjacent color resistors, in a certain range, the display effect is not affected, the width of the shading pattern is smaller than the interval between the adjacent color resistors, so that the aperture ratio of the display panel is further improved, but at the moment, the display effect of the display panel is not affected by the light rays transmitted from the interval between the exposed adjacent color resistors, so that the aperture ratio of the display device is improved while shading the area between the adjacent color resistors of the display device.
In one embodiment, the material of the light shielding pattern includes an inorganic non-metal material, and specifically, an inorganic non-metal material having better light shielding property is selected as the material of the light shielding pattern, thereby improving light shielding property of a region between adjacent pixels of the liquid crystal display panel.
In one embodiment, the material of the light shielding pattern includes one of copper, aluminum, silver, zinc, copper zinc laminated layer, copper titanium laminated layer and copper aluminum laminated layer, by making the material of the light shielding pattern be metal or alloy or metal laminated layer, the metal can reflect and absorb light rays, so as to avoid light rays from emitting, and because the material of the light shielding pattern is metal, the metal has ductility, the bending performance of the display panel is not affected for the liquid crystal display panel needing bending or bending, meanwhile, because the metal can conduct static electricity, and the metal is arranged outside the substrate, the static electricity can be released through the metal, so that the static electricity prevention capability of the liquid crystal display panel is improved, and when the metal is used as the material of the light shielding pattern, the adhesion of the metal material and the substrate is better, so that compared with the problem of dissolution and stripping caused by adopting an organic material, the stripping and stripping caused by adopting the light shielding pattern cannot occur.
In one embodiment, when the metal material is used as the material of the light shielding pattern, since the metal material is disposed outside the substrate and static electricity of the liquid crystal display panel is caused by friction during handling or moving, the light shielding pattern is disposed outside the substrate of the liquid crystal display panel, so that the metal material can directly conduct out the static electricity, thereby avoiding static electricity concentration of the liquid crystal display panel and improving the anti-static capability of the liquid crystal display panel.
In one embodiment, the light shielding pattern is attached to the first substrate, that is, the light shielding pattern is disposed on the first substrate, and the thickness of the light shielding pattern is set to be thinner, so that the aperture ratio of the liquid crystal display panel can be improved, and the light shielding pattern is prevented from falling off.

In one embodiment, the thickness of the light shielding layer is equal to the thickness of the flat layer, that is, when the flat layer is provided, the thickness of the flat layer is only required to be consistent with the thickness of the light shielding layer, so that the light shielding layer is kept flat, and the subsequent formation of the film layer is facilitated.
In one embodiment, the thickness of the flat layer is greater than the thickness of the light shielding layer, that is, when the flat layer is formed, the flat layer is disposed in the gap of the light shielding pattern, and meanwhile, the flat layer is disposed on the light shielding pattern, so that after the light shielding pattern is formed, the flat layer keeps the liquid crystal display panel flat, and when other film layers or other structures are designed, the phenomenon that the other film layers or other structures cannot be formed completely or bend due to uneven areas is avoided, so that display is affected.

In one embodiment, the material of the planarization layer includes an organic material, that is, in order to improve the bending performance of the liquid crystal display panel, the material of the planarization layer may be made of an organic material, so as to improve the flexibility of the planarization layer and the light shielding layer, and at the same time, considering that the planarization layer is disposed in the region corresponding to the color resistance, it is required to make the light transmittance of the planarization layer better, so that the organic material with better light transmittance may be selected as the material of the planarization layer.
In one embodiment, as shown in fig. 2 to 4, the liquid crystal display panel further includes a color resist planarization layer 233, where the color resist planarization layer is disposed between the color resists, that is, when the color resist layer is formed, since the color resist layer is composed of red color resist 232a, blue color resist 232b, and green color resist 232c, a certain interval exists between the color resists, in this embodiment, a black matrix is not disposed between the adjacent color resists, so that the color resist layer needs to be kept flat, and therefore, a color resist planarization layer may be disposed between the color resists, so that the color resist layer remains flat, and when the common electrode layer and other film layers are formed subsequently, the flatness of the other film layers is maintained.
In one embodiment, the material of the color resistance planarization layer is the same as that of the common electrode layer, and the common electrode layer is filled into the adjacent color resistance region, that is, when the color resistance layer is planarized, the common electrode layer can be directly filled into the region between the color resistances, so that the common electrode layer is directly formed on the color resistance layer, the common electrode layer is kept flat while the color resistance layer is kept flat, and meanwhile, the impedance of the common electrode layer can be reduced and the display effect of the liquid crystal display panel is improved due to the increase of the thickness of the common electrode layer.
In one embodiment, the material of the color resistance planarization layer is the same as that of the color resistance layer, that is, when the color resistance planarization layer is formed, adjacent color resistances can be contacted, and then the area between the adjacent color resistances is shielded from light, so that the area between the color resistances is shielded from light by the light shielding pattern while the color resistances emit light normally, and the aperture ratio of the liquid crystal display panel is improved.
